Referring more in details to the drawings:

As required, detailed embodiments of the present invention are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

In the disclosed embodiment of the present invention, the reference numeral 1 generally designates a form tie clamp for retaining a form wall 2 of a concrete form structure in a selected position and spacing from a facing form wall of the concrete form structure during depositing or pouring concrete thereagainst and into a space between facing form walls. The form tie clamp 1 is removably clamped on an elongated member, such as a rod or bar 3, extending outwardly from the form wall 2 and the form tie clamp 1 is in a position having an abutment at one end 4 of each of first and second housings 5 and 6 in engagement with an exterior surface of the form wall 2. The illustrated form tie clamp 1 includes clamping means illustrated as first and second housings 5 and 6 having cavities 7 and 8 respectively therein to receive and retain first and second clamping members 9 and 10 respectively each movable into clamped frictional engagement with a respective portion of the exterior surface of the elongated rod or bar 3 in response to movement of a lever member 11 pivotally mounted on one of the housings, for example the first housing 5, and having laterally spaced arms 12 and I3 pivotally mounted on one end 14 of the lever member 11 and engageable with the other or second housing 6. A keeper member 15 is pivotally mounted on the lever member 11 and is selectively engageable with the rod or bar 3 thereby retaining the lever member 11 and the arms 12 and 13 in position thereby holding the clamping members 9 and 10 in frictional and clamped engagement with the rod or bar 3 and latch means 16 are mounted on one of the housings, for example the second housing 6, and engageable with the other or first housing 5 for cooperating with the keeper member 15 to hold the first and second housings 5 and 6 in position with the clamping members 9 and 10 in clamped and frictional engagement with the rod or bar 3.

The first and second housings 5 and 6 of the clamping means are formed by respective walls arranged to define the cavities 7 and 8 respectively therein. The first housing 5 and the second housing 6 are positioned in facing relation. In the illustrated structure, side walls 17 and 18 define the first housing 5 and the second housing 6 respectively. Opposite ends 19 and 20 of the first housing 5 are closed by suitable end walls to define the cavity 7 in the first housing 5. Opposite ends 21 and 22 of the second housing 6 are closed by suitable end walls to define the cavity 8 therein the opposite end walls of the first and second housings 5 and 6 each have a respective passage or slot therein to permit the rod or bar 3 to extend therethrough.

The side walls 17 and 18 of the first and second housings 5 and 6 respectively may be any suitable shape to cooperate with the respective end walls to define the cavities 7 and 8 respectively therein. In the illustrated structure, the side walls 17 and 18 are semi-circular in cross-section and the side wall 17 has opposite side flanges 23 and 24 extending outwardly therefrom. The side wall 18 has opposite side flanges 25 and 26 extending outwardly therefrom. The side flanges 23 and 24 extending from the side wall 17 are positioned in facing relation with the respective adjacent side flanges 25 and 26 respectively extending from the side wall 18 when thefirst and second housings 5 and 6 are positioned in a closed position.

The first and second clamping members 9 and 10 of the clamping means are positioned in the cavities 7 and 8 of the first and second housings 5 and 6 respectively. The first and second clamping members 9 and 10 have facing surfaces defining elongated recesses 27 and 28 respectively therein. The recessed defining surfaces are each frictionally engageable with a respective opposite portion of the exterior surface of the elongated rod or bar 3.

The first clamping member 9 has opposite ends 29 and 30 engageable with the end walls at the opposite ends 19 and 20 of the first housing 5. The second clamping member 9 has opposite ends 31 and 32 engageable with the end walls defining the opposite ends 21 and 22 respectively of the second housing 6 whereby the first clamping member 9 is retained within the first housing 5 and the second clamping member is retained in the second housing 6 when in clamped frictional engagement with the elongated rod or bar 3.

The clamping members 9 and 10 may be formed of any suitable resilient material adapted to conform to the shape of the exterior surface of the elongated rod or bar 3 extending outwardly from the form wall 2. Hard rubber and various plastics have been found to provide the desired characteristics of sufficient deformation to conform to the exterior surface of the elongated rod 3 when same is a deformed reinforcing rod, such as used in concrete construction. Hard rubber and the plastics have a substantially higher coefficient of friction when in engagement with metal, such as the elongated reinforcing rod or bar 3, than the cofficient of friction of metalto metal engagement.

Means are mounted on one of the first and second housings 5 and 6 and in engagement with the other of the first and second housings 5 and 6 for selectively moving the housings one toward the other and thereby moving the first and second clamping members 9 and 10 into clamped engagement with the respective portion of the exterior surface of the elongated rod or bar 3 extending outwardly from the respective form wall 2.

In the illustrated structure, the means for moving the clamping members 9 and 10 into clamped and frictional engagement with the rod or bar 3 includes a standard extending outwardly from the side wall 17 of the first housing 5. The standard is positioned intermediate the opposite ends 19 and 20 of the side wall 17. The standard is illustrated as being formed of laterally spaced ears 33 and 34 extending substantially radially outwardly from the side wall 17 of the first housing 5 to receive the lever member 11 therebetween.

The lever member 11 is pivotally mounted on the standard and in the illustrated structure, is positioned between the ears 33 and 34 and the lever member 11 has the one end 14 and an other end 35 thereof each positioned on respective opposite sides of the standard. The lever member 11 is illustrated as an elongated planar member positioned between the spaced ears 33 and 34 and pivotally mounted thereon, as by a suitable shaft 36 mounted on and extending between the ears 34 and 33.

The lever member 11 has means pivotally mounted on the one end 14 thereof and engageable with the second housing 6 whereby movement of the other end 35 of the lever member 11 toward the first housing 5 moves the second housing 6 toward the first housing 5 to thereby move the clamping members 9 and 10 into clamped and frictional engagement with respective portions of the exterior surface of the rod or bar 3.

in the illustrated structure, the arms 12 and 13 have respective portions 37 and 38 thereof pivotally mounted on the one end 14 of the lever member 11.

The arm 12 has opposite end portions 39 and 40 extending from respective opposite ends of the intermediate portion 37. The opposite ends portions 39 and 40 of the arm 12 extend through the facing side flanges 23 and 25 of the first and second housings 5 and 6 respectively. The second arm 13 has opposite end portions 41 and 42 extending from respective opposite ends of the intermediate portion 38 thereof and extending through the facing side flanges 24 and 26 of the first and second housings 5 and 6 respectively. The opposite end portions 39 and 40 of the first arm 12 have enlarged portions 43 and 44 engageable with an outwardly facing surface of the side flange 25 of the second housing 6. The opposite end portions 41 and 42 of the second arm 13 have enlarged portions 45 and 46 thereon and engageable with the outwardly facing surface of the side flange 26 of the second housing 6 whereby the arms 12 and 13 move the side flanges 25 and 26 of the second housing 6 toward the side flanges 23 and 24 respectively of the first housing side in response to movement of the lever member 1 1. The enlarged portions are each illustrated as a suitable nut mounted on a threaded end of the respective end portion.

The form tie clamp 1 includes means associated with the first and second housings 5 and 6 respectively and with the means for moving the clamping members 9 and 10 into clamped frictional engagement with the rod 3 for retaining said clamped frictional engagement of the clamping members 9 and 10 with the exterior surface of the rod 3. In the illustrated structure, the keeper member 15 has one end 47 thereof pivotally mounted on the lever member 11 adjacent the other end 35 thereof. The other end 48 of the keeper member 15 has a return bend portion engageable with and surrounding at least a portion of the rod 3 and thereby maintaining the other end 35 of the lever member 11 in a selected spaced relation with the rod or bar 3.

The latch means 16 includes latch members 49 and 50 pivotally mounted on the side flange 25 of the second housing 6 and positioned adjacent the opposite end portions 39 and 40 respectively of the arm 12. Latch members 51 and 52 are also pivotally mounted on the side flange 26 of the second housing 6 and are positioned adjacent the end portions 41 and 42 respectively of the second arm 13. The latch members 49 and 50 are engageable with the side flange 23 of the first housing 5 and the latch members 51 and 52 are engageable with the side flange 24 of the first housing 5.

Each of the latch members has resilient means associated therewith and engageable with an outwardly facing surface of the respective side flange of the first housing 5 for urging the respective facing side flanges toward each other. In the illustrated structure, a washer 53 is sleeved on each of the latch members and is engaged by one end of a spring 54 having the other end thereof in engagement with an enlarged end portions 55. In the illustrated structure, the enlarged portion 55 is a nut mounted on a threaded end portion of the respective latch members.

In using a form tie clamp constructed as illustrated and described, the first and second housings 5 and 6 are positioned in surrounding relation with a reinforcing rod or bar 3 extending -outwardly from the respective form wall 2. The one end 4 of the form tie clamp 1 is positioned in engagement with an exterior surface of the form wall 2 and the other end 35 of the lever member 11 is moved toward the reinforcing rod or bar 3.

The enlarged portions 43, 44, 45, and 46 thereby move the second housing 6 toward the first housing 5 and move the clamping members 9 and 10 into frictional and clamping engagement with respective portions of the exterior surface of the elongated rod-or bar 3. The keeper member is then moved to a position having the other end portion 48 thereof surrounding the rod 3. The latch members 49, 50, 51 and 52 are each moved to a position having the respective washer 53 thereon in engagement with the outwardly facing surface of the respective side flange of the first housing 5. The nuts defining the enlarged end portions 55 may be tightened as desired to compress the spring 54 and thereby hold the housings 5 and 6 in position with the clamping members 9 and 10 therein in clamped and frictional engagement with the rod or bar 3.

It is to be understood that while I have illustrated and described one form of my invention, it is not to be limited to the specific form or arrangement of parts herein described and shown.
